The present invention relates to improvements in closure fasteners andhas reference more particularly to a concealed casement fastener.

One of the important objects of the present invention is to provide a.fastener for association with windows that either swing inwardly oroutwardly, the fastener being of such construction as to be concealedand yet be positive and eflicient in holding the casement window closedagainst accidentally swinging open.

Still a further object is to provide a casement window fastener whereinthe parts are arranged as to permit curtain shade rollers and bracketsto be properly mounted on the casement window frame whereas with the useof the surface bolts now employed on casement windows, considerabledifficulty is experienced in handling curtain shade rollers.

A further object is to provide a casement window fastener of the abovementioned character which is simple in construction, inexpensive, strongand durable and further well adapted to the purposes for which it isdesigned.

Other objects and advantages will become apparent during the course ofthe following description.

In the accompanying drawing, forming a part of this specification, andin which like numerals indicate like parts throughout the same:

catch for association with a casement window sash that swings inwardly,

Figure 7 is a top plan view thereof,

Figure 8 is a view similar to Figure 6 illustrating a type of springcatch for association with a casement window sash that swings outwardly,

Figure 9 is a top plan view thereof, and

Figure 10 is a fragmentary side elevation of the upper portion of adouble casement window showing my improved fastener associatedtherewith.

In the drawings wherein for the purpose of i lustration is shown apreferred embodiment of my invention, the numeral 1 designates acasement window, the sash thereof being designated by the numeral 2 andthe same is adapted to swing inwardly.

The closure fastener associated with this type of casement windowincludes a keeper plate 3 that is secured in a rigid manner to the underside of the top rail of a window frame as shown in Figure 2 and thisportion at of the window frame is formed with a recess 5 with whichcommunicates the slot 6 formed in the forward edge portion of the keeperplate 3.

The forward edge of this keeper plate is bent upwardly as at 7 andprojects beyond the front face of the upper jamb of the window frame orcasing.

Cooperating with the keeper plate 3 is the spring catch shown generallyat 8 in Figures 6 and 7. This spring catch is formed from a relativelywide strip of spring metal 9 that is bent back upon itself at its innerend as at 10, lateral extensions 11 being. formed on the opposite sideedges of the bent back portion 10 for attachment to the upper edge ofthe inwardly swinging window sash 2.

The forward ed e port-ion of the strip 9 is directed upwardly to form anose 12 that cooperates with the slot 6 formed in the keeper plate 3 andthe recess 5 to lock the window sash against accidentally swinging open.

The forward end of the spring strip forwardly of the nose 12 is formedwith an opening 13 to accommodate a chain 14: which when pulled todisengage the nose 12 from the slotted keeper plate whereby to permitthe window sash 2 to be swung inwardly.

When the window sash is swung back into position within the casing 1,the beveled nose will automatically lock in the locked keeper plate tohold the window sash in closed position. v p I 7 Where the window sashswings outwardly, a slightly modified form of fastener is employed andto this end, the keeper plate 15 is formed adjacent its inner end with aslot 16 for communication with a recess 17 formed in the bottom face ofthe upper jamb 18 of the window casing and the keeper plate 15 isrigidly secured to the bottom face of the outer edge portion of thisjamb 18 as shown in Figure 3. y

The outer en'dof the kee er plate is bent upwardly as at 19 and pro ectsbeyond the outer end or edge of the upper j amb 18. The spring catch forassociation with said keeper plate 15 is shown generally at 20 inFigures 8 and 9 as the same is also formed from a relatively wide stripof spring metal that includes a body portion 21.

The outer end portion of the strip is bent back upon itself as at 22 andlateral extensions 23 are formed at the side edges of the bent backportion 21 to provide ameans for attaching the c'ateh to the upper edgeof the outwardly swinging window sash.

Upon referring to Figure 3 it will be observed that the inner face ofthe upper edge portion of the outwardly swinging window sash is cut awayas at 25 for a purpose to be presently described.

The inner end portion of the strip from which the fastener 20 isconstructed is bent ordirected upwardly to form a beveled nose 26 whichcooperates with the slot 16 and the recess 17. The inner end of thespring strip then extendsdownwardly as at 27 and thence laterally at 28,the downwardly disposed portion 27 and a part of the nose 26 arearranged for operation within the out out portion 25 while the laterallyextending portion 28 projects inwardly of the window sash and a chain 29is attached thereto for facilitating the disengagement of the bevelednose 26 from the notch keeper plate when it is de-.

sired to swing the window sash upwardly to an open position.

Manifestly when the window sash is swung inwardly, the beveled nose 26will automatically engage within the notch 16 and the recess 17 forlocking the window sash in closed position. I g

In Figure 10 of the drawings, I have shown the closure fastener as beingassociated with one ofthe window sashes of a double casement window. InFigure 1, the casement window fastener is arranged at the side of aninwardly "swinging window sash and the actuating chain extends throughan eye "30 that is secured on the sash and a ring 31 is attached to thelower end of the chain to permit upper gripping and actuating of thesame.

The provision of a casement window and fastener of the above mentionedcharacter will obviate the use of the usual surface bolts andfurthermore by arranging the fastener so that the major portion thereofis concealed, the curtain shaped bracket may be properly attached on theeasement window to permit the proper hanging of the curtain shaderollers. The simplicity of my improved fastener enables the same to beconstructed and installed at a very low cost and furthermore the samewill at all times be positive and efficient incarrying out the purposesfor which it is designed.

lVhile I have shown the preferred embodiment or" my invention, it is tobe understood that various changes in the size, shape and arrangement ofparts may be resorted to without departing from the spirit of theinvention and the scope of the appended claim.

Having thus described my invention, what I claim as new is: Y

A window sash fastener of the class described, a keeper plate forattachment to the inner side edge of the window casing, said keeperplate being formd with a slot, the adjacent portion of the casing beingformed with a registering recess, a spring catch at tached to theadjacent end of the swinging window sash, said catch comprising a stripof springmetal bent back upon itself at one t end for attachment to theedge of the window sash, an outwardly projecting nose formed from thespring strip of metal for cooperation with the slot in the keeper plateand the recess in the window casing to normally look the window sashagainst swinging movement, suitable means attached to the free end ofthe spring strip to forcibly disengage the nose from the notched casingand the slotted keeper plate, the free end of the keeper plate beingbent laterally to permit the free sliding movement of the nosethereover, the window sash being cut out to accommodate said springcatch. 7 p

In testimony whereof I atfix my signature.

LAMIR PARKER.
